Tip

Tip is a tip calculator application for iOS.

Features

• User can enter a bill amount, choose a tip percentage, and see the tip and total values.
• Settings page to change the default tip percentage.
• UI animations
• Remembering the bill amount across app restarts (if <10mins)
• Using locale-specific currency and currency thousands separators.
• Making sure the keyboard is always visible and the bill amount is always the first responder. This way the user doesn't have to tap anywhere to use this app. Just launch the app and start typing.
• Split between people
• Customize default percentages depending on experiences (terrible, satisfactory, excellent)
• Resets to defaults settings
• Launch screen
• UI/UX design (simple)
• Clears all textFields and labels when bill is empty (or zero)

Things to Improve

• Use AutoLayout to satisfy multiple screen sizes
• There should be a better way to handle SettingsViewController (instead of using a singleton)
• Perhaps modify Tip class and add another class to split responsibilities
• Display a warning to user before actually resetting to defaults
• Notify user (some how) when changing default values
